"All com.android.support libraries must use the exact same version specification" when compiling android.support:appcompat-v7:25.2.0

After updating Android Studio to Version 3.1.2 I'm getting an error in my app's build.gradle:
All com.android.support libraries must use the exact same version specification (...). Found versions 28.0.0-alpha1, 26.1.0. Examples include com.android.support:asynclayoutinflater:28.0.0-alpha1 and com.android.support:animated-vector-drawable:26.1.0
This is my gradle:
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion '27.0.3'
defaultConfig {
applicationId "org.hopto.****.musicplayer"
minSdkVersion 23
targetSdkVersion 25
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.2.0'
compile 'com.android.support:design:25.2.0'
compile 'com.cleveroad:audiowidget:0.9.0'
compile 'com.google.android.gms:play-services-ads:10.2.0'
compile 'com.android.support:recyclerview-v7:+'
testCompile 'junit:junit:4.12'
}
I've tried solving this by adding the following lines:
compile 'com.android.support:asynclayoutinflater:25.0.0'
compile 'com.android.support:animated-vector-drawable:25.0.0'
I've also tried this with different version, eg 25.2.0 and 25+, but none of this worked.

You are using the following support libraries:
compile 'com.android.support:appcompat-v7:25.2.0'
compile 'com.android.support:design:25.2.0'
compile 'com.android.support:recyclerview-v7:+' //error here
As you can see, your recyclerview library is using '+' which is the latest version available, that is 28.0.0-alpha1 or 26.1.0 (stable). For the rest you are using 25.2.0, thus the error with the version mismatch.
The solution is to either change recyclerview version to 25.2.0 or everything to 26.1.0 (including the recyclerview).
Side note: you should avoid using '+' in version numbers as you may come up with unexpected behavior when your libraries update.

Android Studio dex.DexException:

Randomly got this error during my build (debug or production) in the morning.

It has been 10hours and I have tried:
1) Updated my Android SDKs
2) Updated my Google Repository
3) Updated everything else as well.
4) Cleaned and Rebuild the project with no errors.
5) Went through my external dependency tree, didn't find any duplicate libraries.
Here is my gradle content:

compile 'com.google.firebase:firebase-messaging:10.2.1'
compile 'com.android.support:recyclerview-v7:25.0.0'
}
apply plugin: 'com.google.gms.google-services'
Running out of ideas and google result pages for a solution. Does anybody experienced find something wrong with the libraries I use or the versions?
Thanks!

remove this line = compile 'com.android.support:design:25.0.0'
if it doesn't work please add
dexOptions {
preDexLibraries = false }
to your build.gradle file

Solution found.
Looking at the error I googled and found this.
Then went to the Branch documentation and found this here which stated:
Note that if you don’t plan to use the Fabric Answers integration, you
can use the following line:
compile ('io.branch.sdk.android:library:2.+') {
exclude module: 'answers-shim'
}
This answers-shim is also in the stacktrace.
I wonder where is that module then duplicated?

Android - duplicate entry: com/google/android/gms/internal/zzafz.class Error

I got this error when I run the code ->
Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'.>
com.android.build.api.transform.TransformException:
java.util.zip.ZipException: duplicate entry:
com/google/android/gms/internal/zzafz.class
I have no idea what does it means and do I fix it. I need your help guys
I have treid several things but nothing really helped, I added "multiDexEnabled true" and that cause to that error.
Before that error O had "android error finished with non-zero exit value 2". After I added "multiDexEnabled true", it gives me this error:
"duplicate entry: com/google/android/gms/internal/zzafz.class Error"
How can I fix it, any help would be appreciated!
this is my Manifest
apply plugin: 'com.android.application'

compile 'com.firebase:firebase-client-android:2.3.1'
compile 'com.google.firebase:firebase-auth:9.2.1'
}
apply plugin: 'com.google.gms.google-services'

remove compile 'com.google.android.gms:play-services-maps:9.6.1' and clean-build the project

You are including both the legacy Firebase API:
compile 'com.firebase:firebase-client-android:2.3.1'
and the new Firebase APIs:
compile 'com.google.firebase:firebase-database:9.2.1'
compile 'com.google.firebase:firebase-auth:9.2.1'
They should not be used together. Remove firebase-client-android:2.3.1 and follow the instructions in the Firebase Upgrade guide.
It is also important to use the same versions of Firebase and Play Services libraries. Don't use 9.6.1 of play-services-maps and 9.2.1 of the Firebase libs. The latest versions available are 10.0.1. Consider updating all of your dependencies to use the latest versions.
Update:
I copied the dependencies you posted and was able to reproduce the error. After I replaced the dependencies with these, the error was resolved. Do these not work for you?
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.3.0'
compile 'com.google.android.gms:play-services-maps:10.0.1'

Failed to resolve message for support version nowhere referenced in code

I have wasted a full day, and am nowhere close to a solution.
This morning, I decided to add LeakCanary to check leaks in the android app we are developing. I usually work in offline mode as it speeds up builds. After adding it as a dependency, I disabled offline mode.
Within a minute I got an error saying -
Failed to resolve: com.android.support:appcompat-v7:25.0.0
Now currently, we are working with -
compileSdkVersion 23
buildToolsVersion "23.0.3"
and all our android support libraries, both v4 and v7, use 23.1.1
So I thought maybe the LeakCanary library internally uses 25.0.0, so I removed the library from build.gradle.
But the error persisted.
I have tried -
Closing and restarting Android Studio.
Closing and reopening the project in AS.
Invalidating caches and restarting AS.
Clean build.
In effect, my code is exactly similar to what it was yesterday when it was building and running properly, but today it just doesn't seem to go.
What may be the issue?
EDIT
Here is build.gradle -

As per my observation it seems like you haven't updated Android SDK platform and Android Build Tools to version 25.
First of all download and install android sdk platform and build tools from SDK Manager and use the following lines in your build.gradle(module app)
compileSdkVersion 25
buildToolsVersion "25.0.0"
Also update dependencies according to that.
It should work then

Plz anyone help us to fix that issue
Advance thanks

I upgraded all my Android SDK tools (including "Support Repository"), however, I still got the error
Gradle sync failed: Could not find recyclerview-v7.jar (com.android.support:recyclerview-v7:24.1.1)
I then did the following :
targetSdk 24 (was 23)
buildToolsVersion: "24.0.3" (was 24.0.0)
deleted the folders within /.gradle/caches I have windows and the complete path is C:\Users\USERNAME\.gradle\caches
THEN the project built without error !!

Change this
compile 'com.android.support:design:24.0.0-beta1'
compile 'com.android.support:support-v4:24.0.0-beta1'
compile 'com.android.support:recyclerview-v7:24.1.1'
compile 'com.android.support:cardview-v7:24.0.0-beta1'
to this
compile 'com.android.support:design:24.1.1'
compile 'com.android.support:support-v4:24.1.1'
compile 'com.android.support:recyclerview-v7:24.1.1'
compile 'com.android.support:cardview-v7:24.1.1'
you have to use same version.

Replace with these
android {
compileSdkVersion 23
buildToolsVersion "23.0.1"
defaultConfig {
applicationId "com.stackdemo"
minSdkVersion 11
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false

}
}

compile fileTree(include: ['*.jar'], dir: 'libs')

compile 'com.android.support:multidex:1.0.0'
}

I have the same issue and once i update Build tool version and android studio. Issue is resolved. Defiantly it is due to older build tool version.

I had this issue with a sample project from Android Developers. I updated all of the libraries in. the gradle file to latest versions then cleaned & rebuilt the project. All is working fine now.
Probably a good idea to make sure all of your sdk's are up to date too
